# Troubleshooting Steps

To begin, install the `usethis` package:

```r
pacman:p_load(usethis)

# or: 
# install.packages("usethis")
# followed by 
# library(usethis)
```

---

# Troubleshooting Steps

Next, run the following:

```r
library("usethis")
git_sitrep()
```

View the output: 
do you see any Xs or lines saying "lacks recommended scopes", "error", or "can't retrieve"?

# Create a Personal Access Token (PAT)

To fix these errors, we'll create a .hi-medgrn[Personal Access Token (PAT)] on GitHub.

The below code will open a browser window - follow the steps to create a PAT

```r
usethis::create_github_token()
```

---
# Add a PAT to RStudio

Back in RStudio, run

```r
 gitcreds::gitcreds_set()
```

Follow the prompts to add/replace existing credentials, pasting in the PAT.

---
# Check PAT

Once added, run `git_sitrep` one last time to verify.

If all looks good, try pushing again!
